APPARATUS FOR PASTEUBIZING LIQUIDS.

Original application filed February 2, 1926, Serial No. 85,471. Divided and this application filed June 21, 1926. Serial No. 117,446.

My invention relates to the treatment of liquids, for the removal therefrom of deleterious gases, said removal occurring while the liquid is being pasteurized or otherwise 6 treated, and has for its objects to provide an improved apparatus for accomplishing this purpose Without destroying or materially changin the physical or chemical structure of the liquid, the apparatus involved being extremely simple and highly efficient.

The present case is a division of an application filed by me February 2, 1926, Serial No. 85,471, and is intended to cover the apparatus disclosed in said parent application for carrying out the method disclosed therein. 1

The apparatus hereinafter described and illustratedin the accompanying drawings, shows a form readily applicable to the treat- 0ment of milk or cream, in which harmful gases are known to be present. These gases may be the result of organic changes, or they may be the outcomeof bacteria growthi, caused by absorbed flavors or improper feeding of the dairycattle. Much trouble is encountered from the latter, and it is a common objection in many sections ofthe country between seasons,when the cattle crave change of diet and feed on weedy plants. Undesirable flavors from other causes are known to be present in milk and cream practically the entire year through, and can be traced to the feeding of turnips, silo, kale, certain legumes, etc.

taken on the line V V of Figure2.

Figure 6 is a detail view partly in section of the suction pump employed with the apparatus.

Figure 7 is a sectional view of the pasteurizer showing a slightly modified construction.

Similar numerals of reference denote corresponding parts in the several. views.

M In. the said drawings, referring more paw ticularly to Figure 1, the reference numeral 1 denotes a pipe for supplying the liquid to be treated, the same discharging into the upper tank 2 of a regenerator 3 of the general type disclosed in Letters Patent No. 1,073,989, granted to me September 23, 1913, said liquid after passing through said regenerator discharging into the lower tank 4 thereof, from which it is led by pipe 5 into the pasteurizer 6 hereinafter described, wherein it is treated for the renewal of gases, and is discharged therefrom through pipe 7 into the lower end of the regenerator 3 up which it passes to impart its heat to the incoming liquid, and from which it is discharged through the pipe 8 to the cooler 9, from which leads a pipe 10 to carry away the treated liquid.

Referring specifically to the pasteurizer 6, the same comprises a metal base 11 sup ported on legs 12, fastened to which is a cylindrical lining 13 which forms an integral part of a'heating jacket 14 constructed with a helical circulating channel 15. A circulating pump 16 is connected with suction pipe 17 and discharge pipe 18, which latter re- .turns to the jacket 14 through connecting pipe 19. Disposed in discharge pipe 18 is a perforated steam pipe 20 having a controlling valve 21. Conveniently located at the upper portion of the jacket 14 is a pressure 5 release valve 22 and a pressure gage 23, their function being to control and indicate the pressure in the jacket 14, which in turn will reflect the temperature vof the circulating medium used. a

On top a of the cylindrical lining 13 is mounted a cover 24 having an annular chan nel 25 merging into a discharge outlet 26 to which is attached the pipe 7 and in which is located a temperature indicating device 28. In the center of the cover 24 is located a suitable packed bearing 29, while through Figure 4 is a detailperspective view partly the center of the base 11 is projected a stationary pipe 30 extending upward within. Figure 5 is a horizontal sectional view,

the pasteurizer to a suitable height to permit correct functioning. This pipe serves, first, asa vertical guide for the exhaust rotor, hereinafterdescribed; and, secondly, as a draw-oft pipe connected to the suction pump 31, shown in detail in Figure 6, the same being driven by a suitable electric motor 32 and dischar ing through pipe 33. Formed centrally in the base 11, surrounding the pipe 30, is a chamber 34 into which the liquid to be: treated is introduced by ipe 5, said 1nd in the bottom of said chamber, a rotor within said chamber comprising horizontal disks and horizontal and vertical vanes. for forcing the liquid peripherally upward in said chamber, and a drive for said rotor supporting the same freely in said chamber.

4. An apparatus for pasteurizing liquids, comprising a chamber, means for applying heat to said chamber, an inlet for liquid to be treated at the bottom of said chamber, a pipe projecting centrally upward part-way in said chamber, an exhaust pump connected with said pipe, a rotor within said chamber for driving the liquid centrifugally upward therein, a hollow shaft fixed to said rotor, fitting over said pipe and having apertures in the upper portion of the same, and means for supporting and rotating said shaft.

5. An apparatus for treating liquids, comprising a chamber for containing liquids to be treated, a rotor within said chamber, a

hollow vertical shaft for said rotor, antifriction means for supporting the upper end of said shaft, means for rotating said shaft and rotor at a sufiiciently high rate of speed prising a chamber for containing liquids to be treated, a rotor within said chamber, a hollow vertical shaft for said rotor, means for rotating said shaft and rotor at a sufficiently high rate of speed to throw the liquids away from'said shaft and a vacuum producing device for drawing gases and vapors emanating from the liquids through said hollow shaft.

7. An apparatus for treating liquids, comprising a chamber for containing liquids to be treated, means within said chamber for strongly rotating said liquid to form a central zone void of liquids and vacuum producing means connected to said zone for withdrawing gases and vapors emanating from said liquids.

In testimony whereof I hereunto aflix my signature.
